Do you mean electron, if an electron moves to higher energy level then it has low electronegative and its hard for that element to lose an electron. Atomic radius increases

The electrons in an atom exist in various energy levels. When an electron moves from a lower energy level to a higher energy level, energy is absorbed by the atom. When an electron moves from a higher to a lower energy level, energy is released (often as light).

Homologous recombination is a unique feature of meiosis whose purpose is to increase genetic diversity during reproduction. What

tigry1 [53]

Answer:

The correct answer will be-

1. Homologous recombination- crossing over

2. Occur-during pachytene of meiosis I of gamete formation.

Explanation:

The basis of diversity of organism present on earth lies in the sexual mode of reproduction possessed by the organism to produce offspring. The sex cells involved in the reproduction are formed by a process called meiosis.

During the formation of gametes, at the pachytene stage of meiosis I take place a mechanistically conserved process which leads to the exchange of DNA segment between non-sister chromatids called crossing over through a process known as homologous recombination. This exchange of genetic material in the homologous chromosomes increase the genetic diversity of the organism on the earth.

In your opinion, how do you think Lamarck's ideas were taken? justifies

PolarNik [594]

Answer:

they considered valid but a certain idea of acquired characteristics being inherited was rejected

Explanation:

his theory was that if the environment demanded a need or use of a structure in an organism it developed it in response to demand leading to natural use or disuse of structures which he said that these new structures would be passed to their offspring leading to emergence of a new species. scientists accepted that the environment has a role in directing phenotypic changes in an individual taking a body builder for example since his muscles will become huge due to continuous use of the muscles in exercises

but scientists rejected his theory of these acquired characteristics were inherited since phenotypically acquired characteristics that do not affect the genotype of an individual can't be inherited
